Semi-mounted central delivery rakes
Intended for use on medium and large farms, the latest Kuhn GA 7631 and GA 8131 semi-mounted central-delivery rakes come with working widths from 6.7m to 7.5m and 7.1m to 8m respectively.
The first to break cover is AURA, a self-propelled ‘feeding solution’ that loads, weighs, mixes, distributes and even ‘pushes up’ feed to the barrier. Part of the ALFS (Autonomous Livestock Feeding System) that started as a concept in 2015, the finished version recently walked away with an innovation award at the recent French Space 2020 Expo.
Up front, a rotary cutterhead and conveyor system – like the one already used on the company’s full-sized mixer wagons – cuts silage directly from the clamp face and delivers it to the machine’s 3 cubic metre capacity tub.
Said to be suitable to feed a mob of up to 280 animals, the AURA tips the scales at 6.2 tonnes empty. It can travel at speeds of up to 7km/h around the yard or 2 km/h when feeding.
Currently powered by a 56hp diesel engine, Dairy News understands that a hybrid option is in the pipeline.
This will use the engine for loading and mixing and then switch to an ‘electric mode’ for feeding – helping to reduce both noise and emissions.
Guidance at the clamp is taken care of by GPS/RTK in conjunction with an odometer, while at the feeding area, LIDAR and the odometer is the chosen solution.
